Manually releasing the parking brake using
the switch helps your ve hicle start slowly and
smoothly when facing down hill on steep hills.
■Parking Brake1 Braking
When you depress the brak e pedal, you may hear a
whirring sound from the engine compartment. This is
because the brake system is in operation, and it is
normal.
1 Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parking brake. This is normal.
The brake pedal may slightly move due to the electric
parking brake system opera tion when you apply or

You cannot apply or release the parking brake if the
battery goes dead. 2 If the Battery Is Dead P. 608
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four
wheels are applied by the VSA ® system until the

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, a nd helps you retain steering control by
pumping the brakes rapidly, much faster than you can.
The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distri bution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Depress the brake
pedal and keep holding the pedal firmly dow n. On dry pavement, you will need to
press on the brake pedal very hard before the ABS activates. However, you may feel
the ABS activate immediately if yo u are trying to stop on snow or ice.
ABS may activate when you depress the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surfaces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correctly if you use a tire of
the wrong size or type.
If the ABS indicator comes on while driving, there
may be a problem with the system. While normal
braking will not be affected, there is a possibility that
the ABS will not be opera ting. Have your vehicle
checked by a dealer immediately.
The ABS is not designed for the purpose of reducing
the time or distance it takes for a vehicle to stop: It is
designed to limit brake lo ckup which can lead to
skidding and loss of steering control.
In the following cases, yo ur vehicle may need more
distance to stop than a vehicle without the ABS:
•You are driving on rough or uneven road surfaces,
such as gravel or snow.
•The tires are equipped with tire chains*.
The following may be observed with the ABS system:
•Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
engine has been started and while the vehicle
accelerates.
•Brake pedal and/or the vehicle body vibration when
ABS activates.
These vibrations and sounds are normal to ABS
systems and are no cause for concern.
* Not available on all models

uuParking Your Vehicle uWhen Stopped
Driving
1When Stopped
NOTICE
The following can dama ge the transmission:
•Depressing the accelerator and brake pedals
simultaneously.
•Holding the vehicle in place when facing uphill by
depressing the accelerator pedal.
•Putting the transmission into ( P before the vehicle
stops completely.
In extremely cold temperatures, the parking brake
may freeze up if applied. If such temperatures are
expected, do not apply the parking brake but, if
parking on a slope, either turn the front wheels so
they will contact the curb if the vehicle rolls down the
slope or block the wheels to keep the vehicle from
moving. If you do not take either precaution, the
vehicle may roll unexpected ly, leading to a crash.

The rear camera view is restricted. You cannot see
the corner ends of the bumper or what is underneath
the bumper. Its unique le ns also makes objects
appear closer or farther than they actually are.
Visually confirm that it is safe to drive before backing
up. Certain conditions (such as weather, lighting, and
high temperatures) may also restrict the rear view. Do
not rely on the rearview display which does not give
you all information about conditions at the back of
